Answer 1

Răspuns:

a - 8/8

b - 39/22

c - 1/13

d - 11/33

Explicație pas cu pas:

a) 7/8 - 1/8 = 6/8

6/8 + 1/4 = 6/8 + 2/8 = 8/8 = 1 (un întreg)

b) 5/6 + 7/6 = 12/6

12/6 - 1/7 = 84/42 - 6/42 = 78/42 = 39/22

c) 7/3 - 4/3 = 3/3

3/3 - 12/13 = 39/39 - 36/39 = 3/39 = 1/13

d) 9/11 + 2/11 = 11/11

4/3 - 11/11 = 44/33 - 33/33 = 11/33
